List of CVEs: CVE-2019-11660
This module exploits the trusted $PATH
environment
variable of the SUID binary omniresolve
in Micro Focus
(HPE) Data Protector A.10.40 and prior. The omniresolve
executable calls the oracleasm
binary using a relative
path and the trusted environment $PATH
, which allows an
attacker to execute a custom binary with root
privileges.
This module has been successfully tested on: HPE Data
Protector A.09.07: OMNIRESOLVE, internal build 110, built on
Thu Aug 11 14:52:38 2016; Micro Focus Data Protector
A.10.40: OMNIRESOLVE, internal build 118, built on Tue May
21 05:49:04 2019 on CentOS Linux release 7.6.1810 (Core) The
vulnerability has been patched in: Micro Focus Data

Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Basic Usage
Note: To run a local exploit, make sure you are at the msf prompt.
Also, to check the session ID, use the sessions
command.

Knowledge Base
Description
This module exploits the trusted $PATH
environment
variable of the SUID binary omniresolve
in
Micro Focus (HPE) Data Protector A.10.40 and prior.
The omniresolve
executable calls the oracleasm
binary using
a relative path and the trusted $PATH
, which allows an attacker
to execute a custom binary with root
privileges.
